No interior lights anywhere or windows last night i lost all interior lights, odometer backlight and radio display. also the windows but the radio stayed on just no display. I was thinking this is caused by the BCM. does anyone think i may have more than one problem??

I checked the fuses last night they were all fine and im guessing that IP dimmer fuse is all or nothing sort of thing since its a fuse. the lights for the odometer and the radio as well as the windows all worked this morning so that led me to believe that its the BCM causing the problem but was looking for advice to see if anyone else thought it was caused by something else.

The BCM has absolutely nothing to do with the dash lighting.
Do your tail lights (running lights not brake lights) work? The dash lighting gets its power through the IP DIMMER fuse which in turn gets power from the TAIL LPS fuse. If your tail lights aren't working then the TAIL LPS fuse is probably the cause.

Instead of guessing, get yourself a test light or multimeter and start tracing. First unplug one of the dash lights and test for power at the socket. Alternatively, you could pull out the radio and test the gray wire in the black 10-pin connector. You can also test for ground although I seriously doubt that is the problem. Assuming you get no power, you should work backwards by testing for power at the IP DIMMER fuse - just because the fuse is okay doesn't mean that power is flowing. If no power at the fuse then check for power at the dimmer switch. The brown wire is the input power from the TAIL LPS fuse and the dark green wire is the output to the IP DIMMER fuse and the lights.
A power windows problem may or may not be caused by the BCM but the dash lights certainly are not related. If you have the common solder joint problem in the BCM, your radio will cut out at the same time as the windows. In that case it's an easy fix. If they don't both cut out at the same time then you'll have some more diagnostics to do.
